[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] The following is for reference. Figures 1-11 This invention describes an air conditioner according to an embodiment of the present invention.

[0040] refer to Figures 1-5 According to an embodiment of the present invention, an air conditioner includes a housing assembly 10, an air guide assembly 14a, and a heat exchange and air supply assembly 20. The housing assembly 10 includes a main housing assembly 1 and a front panel assembly 2. The front panel assembly 2 is connected to the front end of the main housing assembly 1. The housing assembly 10 has an air inlet 111, a main air duct, and two main air outlets 13. The two main air outlets 13 are located at the front end of the housing assembly 10 and are respectively located on the left and right sides of the front panel assembly 2. The main air duct connects the air inlet 111 and the main air outlets 13. The front panel assembly 2 has a secondary air outlet 251 and a secondary air duct 22. The secondary air duct 22 connects the main air duct and the secondary air outlet 251. The secondary air outlet 251 is located on the front side of the front panel assembly 2. The air guide assembly 14a is disposed at the main air outlet 13. The heat exchange and air supply assembly 20 is disposed inside the main housing assembly 1 and includes a heat exchanger assembly and an air duct assembly 201.

[0041] When the air conditioner is working, the air duct assembly 201 can drive the airflow through the air inlet 111 into the interior of the casing assembly 10 and flow toward the heat exchanger assembly. After heat exchange in the heat exchanger assembly, the airflow flows to the main air duct. The airflow after heat exchange in the main air duct can flow out to the room through the two main air outlets 13 to regulate the indoor temperature. The two main air outlets 13 can increase the air outlet area of ​​the air conditioner, which is beneficial to improve the air outlet efficiency of the air conditioner and can also make the air outlet angle of the air conditioner wider to cover more indoor areas.

[0042] By providing an air guide assembly 14a at the main air outlet 13, the airflow at the main air outlet 13 can be guided to better direct the airflow to the left and right sides of the air conditioner, thereby enhancing the airflow effect of the air conditioner to the left and right sides and improving the cooling / heating effect of the air conditioner.

[0043] Furthermore, since the front panel assembly 2 has a secondary air outlet 251 and a secondary air duct 22, and the secondary air duct 22 connects the main air duct and the secondary air outlet 251, at least part of the airflow after heat exchange in the main air duct can also be blown out of the room from the secondary air outlet 251. Moreover, since the front panel assembly 2 is located on the front side of the housing assembly 10 and the two main air outlets 13 are located on the left and right sides of the front panel assembly 2, the air blown out of the secondary air outlet 251 can be closer to the front center of the air conditioner, thereby effectively regulating the temperature in front of the air conditioner, enhancing the uniformity of the indoor temperature, and thus improving the user experience.

[0044] According to the embodiment of the present invention, the air conditioner has an air guide component 14a located in the main air duct and close to the main air outlet 13. By having the air guide component 14a located at the main air outlet 13, the airflow at the main air outlet 13 can be guided to be better directed to the left and right sides of the air conditioner, thereby enhancing the air delivery effect to the left and right sides and improving the cooling / heating effect of the air conditioner. In addition, a secondary air outlet 251 is provided on the front side of the front panel component 2, so that a secondary air outlet 251 is provided between the two main air outlets 13. This allows the air blown out by the secondary air outlet 251 to be closer to the front center of the air conditioner, thereby effectively regulating the temperature directly in front of the air conditioner, enhancing the uniformity of the indoor temperature, and thus improving the user experience.

[0045] refer to Figures 3-5According to some embodiments of the present invention, the air guiding assembly 14a includes an air guiding grille 16, which includes a plurality of grille ribs 1621 spaced apart. The grille ribs 1621 extend in the vertical direction, and a guiding channel is defined between two adjacent grille ribs 1621. The spaced arrangement of the plurality of grille ribs 1621 can enhance the overall structural strength of the air guiding grille 16 to a certain extent. The spaced arrangement of the plurality of grille ribs 1621 and the guiding channel defined between two adjacent grille ribs 1621 can guide the airflow passing through the air guiding grille 16 and make the airflow distribution more uniform.

[0046] In the description of this utility model, "multiple" means two or more.

[0047] refer to Figures 1-5 According to some embodiments of the present invention, the air guide grille 16 includes an air guide bracket 161 and a grille section 162. The air guide bracket 161 is rotatably connected to the housing assembly 10. The grille section 162 has a plurality of grille ribs 1621. The grille section 162 has a side air guide position and a front air guide position. The projection of the housing assembly 10 on the horizontal plane is the housing assembly projection. The left and right central axes of the housing assembly projection extend along the front-back direction and are located in the middle of the housing assembly projection in the left-right direction. The angle between the grille ribs 1621 at the front air guide position and the left and right central axes is smaller than the angle between the grille ribs 1621 at the side air guide position and the left and right central axes (see reference). Figures 3-5 The arrows shown indicate the direction of airflow.

[0048] The air guide grille 16 includes an air guide bracket 161 and a grille section 162, and the air guide bracket 161 is rotatably connected to the housing assembly 10. The air guide grille 16 and the housing assembly 10 can be rotatably connected. By adjusting the angle of rotation of the grille ribs 1621 of the grille section 162, the flow direction of the airflow in the main air duct can be adjusted.

[0049] By making the angle between the grille rib 1621 at the front air guide position and the left and right central axes smaller than the angle between the grille rib 1621 at the side air guide position and the left and right central axes, when the grille rib 1621 is in the front air guide position, it can guide the airflow in the main air duct towards the front center of the air conditioner, thereby bringing the air blown out of the main air outlet 13 closer to the front center of the air conditioner and effectively regulating the temperature directly in front of the air conditioner. When the grille rib 1621 is in the side air guide position, it can guide the airflow in the main air duct over a long distance, guiding the airflow in the main air duct to better direct the airflow towards the left and right sides of the air conditioner, thereby enhancing the airflow effect to the left and right sides of the air conditioner and improving the cooling / heating effect of the air conditioner.

[0050] refer to Figures 3-5According to some embodiments of this utility model, in the front air guide position, the grille portion 162 is located in the position where the main air outlet 13 is closed, and in the side air guide position, the grille portion 162 is located in the position where the main air outlet 13 is open. When the grille rib 1621 is in the front air guide position, the grille portion 162 is located in the position where the main air outlet 13 is closed, which can guide the airflow in the main air duct to flow towards the front center of the air conditioner. This can also guide at least a portion of the airflow in the main air duct to flow towards the secondary air outlet 251, so that more airflow blows towards the front center of the air conditioner, thereby effectively regulating the temperature directly in front of the air conditioner.

[0051] refer to Figures 3-5 According to some embodiments of this utility model, the air guiding assembly 14a includes an air guiding plate 14, which is rotatably disposed at the main air outlet 13 for opening and closing the main air outlet 13. When the air guiding plate 14 is located at the main air outlet 13, it is positioned outside the air guiding grille 16. By rotatably disposing the air guiding plate 14 at the main air outlet 13 for opening and closing the main air outlet 13, the main air outlet 13 can be opened or closed by adjusting the rotation angle of the air guiding plate 14. When the air guiding plate 14 is in the open position of the main air outlet 13, its location outside the air guiding grille 16 better guides the airflow direction, directing the airflow from the main air outlet 13. This ensures that the airflow near the outer side of the main air duct flows more smoothly in a preset direction, improving the airflow efficiency of the main air outlet 13 and reducing the possibility of airflow turbulence.

[0052] When the air guide plate 14 is in the position of closing the main air outlet 13, the air guide plate 14 is located outside the air guide grille 16, which can provide a certain degree of protection for the air guide grille 16. The air guide plate 14 can block some of the external impact force, such as when the equipment is slightly bumped or blown by the wind, reducing the possibility of the air guide grille 16 being directly damaged, extending the service life of the air guide grille 16, and also helping to cover the air guide grille 16, thereby improving the overall aesthetics of the air conditioner.

[0053] It should be explained that the outer side of the air guide grille 16 refers to the side of the air guide grille 16 that is away from the center of the housing assembly 10.

[0054] refer to Figures 3-5According to some embodiments of this utility model, when the air guide plate 14 is positioned with the main air outlet 13 open, the air guide plate 14 is located on the side of the air guide grille 16 away from the front panel assembly 2. The side of the air guide plate 14 facing the air guide grille 16 has a guiding surface 141, which extends obliquely towards the front panel assembly 2 in a direction from back to front. When the air guide plate 14 is positioned with the main air outlet 13 open, the guiding surface 141 on the side of the air guide plate 14 facing the air guide grille 16 and the oblique extension of the guiding surface 141 towards the front panel assembly 2 in a direction from back to front can guide at least a portion of the airflow in the main air duct towards the front of the front panel assembly 2, making the airflow more concentrated and blowing towards the front center of the air conditioner, avoiding the airflow from being dispersed to other unnecessary directions, thereby improving the utilization rate of the airflow and thus more effectively regulating the temperature in front of the air conditioner.

[0055] refer to Figures 3-5 According to some embodiments of this utility model, the air guide plate 14 has multiple air diffusers extending through it along its thickness direction. These diffusers allow airflow to pass through the air guide plate 14, increasing the airflow area. In addition to airflow passing through the space between the air guide plate 14 and the frame, the air diffusers on the air guide plate 14 further facilitate airflow at the main air outlet 13, improving its flow effect. Even when the air guide plate 14 is in the closed position (main air outlet 13), airflow within the main duct can still exit through the diffusers on the air guide plate 14, resulting in a more comfortable airflow at the main air outlet 13 and enhancing the user experience.

[0056] For example, the cross-section of the air diffuser is circular.

[0057] refer to Figures 3-5 According to some embodiments of this utility model, there are two secondary air outlets 251, located at the left and right ends of the front panel assembly 2, respectively. There are also two secondary air ducts 22, located at the left and right ends of the front panel assembly 2. The secondary air duct 22 at the left end connects the corresponding secondary air outlet 251 to the main air duct, and the secondary air duct 22 at the right end connects the corresponding secondary air outlet 251 to the main air duct. Positioning the two secondary air outlets 251 at the left and right ends of the front panel assembly 2 allows airflow to be evenly distributed from both sides of the front panel assembly 2, making the airflow from the secondary air outlets 251 closer to the front center of the air conditioner and more uniform, avoiding uneven airflow distribution that might result from unilateral airflow.

[0058] Two main air outlet ducts 12 are located on the left and right sides of the front panel 24, respectively, allowing airflow to be blown out from the main air outlets 13 distributed on the left and right sides of the front panel 24. This gives the air conditioner a wide air delivery angle. A secondary air duct 22 at the left end connects the main air outlet duct 12 on the left to the corresponding secondary air outlet 251, and a secondary air duct 22 at the right end connects the main air outlet duct 12 on the right to the corresponding secondary air outlet 251. This allows the airflow in the main air outlet duct 12 on the left to flow smoothly through the secondary air duct 22 to the secondary air outlet 251 on the left, and the airflow in the main air outlet duct 12 on the right to flow smoothly through the secondary air duct 22 to the secondary air outlet 251 on the right. This achieves orderly airflow and reduces airflow resistance and the possibility of turbulence.

[0059] refer to Figures 3-5 According to some embodiments of this utility model, the main air duct includes two main air outlet channels 12 arranged along the left and right sides. Each main air outlet channel 12 is provided with an air guide component 14a. The two main air outlet channels 12 are located on the left and right sides of the front panel component 2, respectively. The auxiliary air duct 22 located at the left end connects the main air outlet channel 12 located on the left side with the corresponding auxiliary air outlet 251, and the auxiliary air duct 22 located at the right end connects the main air outlet channel 12 located on the right side with the corresponding auxiliary air outlet 251. By providing an air guide component 14a in each main air outlet channel 12, the airflow in the two main air outlet channels 12 can be effectively guided, and the airflow to the auxiliary air outlet 251 can be regulated. This allows for multiple air guiding modes of the air conditioner to meet different user needs and improve the user experience.

[0060] For example, the air guide assembly 14a includes an air guide grille 16 and an air guide plate 14. The air guide grille 16 includes an air guide bracket 161 and a grille section 162. The air guide bracket 161 is rotatably connected to the housing assembly 10. The grille section 162 has a plurality of grille ribs 1621. The grille section 162 has a side air guide position and a front air guide position. The projection of the housing assembly 10 on the horizontal plane is the housing assembly projection. The left and right central axes of the housing assembly projection extend along the front-back direction and are located in the middle of the housing assembly projection in the left-right direction. The angle between the grille ribs 1621 in the front air guide position and the left and right central axes is smaller than the angle between the grille ribs 1621 in the side air guide position and the left and right central axes. In the front air guide position, the grille section 162 is located in the position where the main air outlet 13 is closed. In the side air guide position, the grille section 162 is located in the position where the main air outlet 13 is open. The air guide plate 14 is rotatably disposed at the main air outlet 13 for opening and closing the main air outlet 13. When the air guide plate 14 is located at the main air outlet 13, the air guide plate 14 is located outside the air guide grille 16.

[0061] When the air guide grille 16 is in the side air guide position and the air guide plate 14 is in the position of opening the main air outlet 13, the air guide grille 16 can guide the airflow in the main air duct to flow better to the left and right sides, so that the air conditioner has a wider air supply angle. At this time, the airflow from the main air duct to the secondary air outlet 251 is correspondingly smaller, and the airflow blown out from the main air outlet 13 can form a wide-area wind field to cover a wider indoor area.

[0062] When the air guide grille 16 is in the front air guide position and the air guide plate 14 is in the position of opening the main air outlet 13, the air guide grille 16 can guide the airflow in the main air duct to flow towards the central part in front of the air conditioner, so that the air supply angle of the air conditioner is smaller. At this time, the airflow from the main air duct to the secondary air outlet 251 is correspondingly smaller, and the airflow is more concentrated and delivered from the main air outlet 13 to the central part in front of the air conditioner, which can make the wind blown out of the main air outlet 13 go further to form a distant wind field.

[0063] When the air guide grille 16 is in the front air guide position and the air guide plate 14 is in the position of closing the main air outlet 13, the air guide grille 16 can guide the airflow in the main air duct to flow towards the central part in front of the air conditioner. At this time, the air guide plate 14 is in the position of closing the main air outlet 13, and the airflow in the main air duct can flow out through the air diffuser holes on the air guide plate 14. At this time, the airflow from the main air duct to the secondary air outlet 251 increases accordingly, which can make the airflow more concentrated and flow towards the central part in front of the air conditioner to form a gentle air field, reduce the discomfort of direct blowing, and improve the user experience.

[0064] refer to Figures 3-5 According to some embodiments of the present invention, the front panel assembly 2 and the main housing assembly 1 together define two main air outlet channels 12 and two main air outlets 13. A secondary air inlet 231 is formed on the side of the front panel assembly 2 facing the main air outlet channel 12. The secondary air inlet 231 connects the corresponding main air outlet channel 12 and the secondary air duct 22.

[0065] For example, the main air duct includes two main air outlet channels 12 arranged along the left and right sides. The two main air outlet channels 12 are located on the left and right sides of the front panel assembly 2, respectively. The auxiliary air inlet 231 of the main air outlet channel 12 on the left side is used to connect the main air outlet channel 12 on the left side with the auxiliary air outlet channel 22 on the left end. The auxiliary air outlet channel 22 on the left end is used to connect the auxiliary air inlet 231 of the main air outlet channel 12 on the left side with the corresponding auxiliary air outlet 251. The auxiliary air inlet 231 of the main air outlet channel 12 on the right side is used to connect the main air outlet channel 12 on the right side with the auxiliary air outlet channel 22 on the right end. The auxiliary air outlet channel 22 on the right end is used to connect the auxiliary air inlet 231 of the main air outlet channel 12 on the right side with the corresponding auxiliary air outlet 251.

[0066] A secondary air inlet 231 is formed on one side of the front panel assembly 2 facing the main air outlet duct 12. The secondary air inlet 231 connects the corresponding air outlet duct and the secondary air duct 22, so that the airflow in the main air outlet duct 12 can flow smoothly through the secondary air inlet 231 to the corresponding secondary air duct 22, and then blown to the front center of the air conditioner through the corresponding secondary air outlet 251.

[0067] refer to Figures 6-10 According to some embodiments of the present invention, the front panel assembly 2 includes a front panel component 23 and a front air outlet frame 21. The front panel component 23 is detachably connected to the front side of the front air outlet frame 21. The front panel component 23 and the front air outlet frame 21 together define a secondary air duct 22. A secondary air inlet 231 is formed in the front air outlet frame 21, and a secondary air outlet 251 is formed in the front panel component 23.

[0068] The front panel component 23 is detachably connected to the front side of the front air outlet frame 21, which facilitates the maintenance or replacement of the front panel component 23 or the front air outlet frame 21.

[0069] A secondary air inlet 231 is formed on the front air outlet frame 21, and a secondary air outlet 251 is formed on the front panel component 23. The front panel component 23 and the front air outlet frame 21 together define the secondary air duct 22, making the airflow smoother and reducing the resistance of the airflow during the flow process. For example, the airflow path can be: the airflow in the main air outlet duct 12 flows into the secondary air duct 22 through the secondary air inlet 231 on the front air outlet frame 21, and then blows towards the front center of the air conditioner through the secondary air outlet 251.

[0070] In some embodiments, a single secondary air duct 22 corresponds to a plurality of secondary air inlets 231 arranged at intervals along the vertical direction. The arrangement of multiple secondary air inlets 231 at intervals along the vertical direction can increase the air intake area of ​​the secondary air inlets 231, so that more airflow can flow into the secondary air duct 22, thereby improving the air outlet efficiency of the secondary air duct 22. It can also allow the airflow in the main air outlet duct 12 to flow into the secondary air duct 22 from the secondary air inlets 231 at different heights. In this way, when the secondary air duct 22 discharges air, the air can be delivered more evenly in the vertical direction, avoiding situations where the local airflow is too strong or too weak.

[0071] refer to Figure 10 and Figure 11In some embodiments, the panel support 25 has a secondary flow port 252. In the airflow direction, the secondary flow port 252 is located downstream of the secondary air inlet 231 and upstream of the secondary air outlet 251. On a reference plane, the flow cross-section of the secondary flow port 252 is smaller than that of the secondary air inlet 231, and the reference plane is perpendicular to the horizontal plane. Because the flow cross-section of the secondary flow port 252 is smaller than that of the secondary air inlet 231, under constant airflow conditions, the airflow velocity at the secondary flow port 252 can be increased, thereby increasing the airflow velocity at the secondary air outlet 251. This reduces the exchange time of hot and cold air at the secondary air outlet 251, thus reducing the possibility of condensation at the secondary air outlet 251 due to excessive temperature difference with the front panel assembly 2.

[0072] refer to Figures 6-10 According to some embodiments of the present invention, the front panel component 23 includes a front panel 24 and a panel support 25. The front panel 24 is detachably disposed on the front side of the panel support 25. The secondary air duct 22 is formed on the panel support 25. The front panel 24 extends in the left-right direction. The secondary air duct 22 has a first sidewall 221 and a second sidewall 222 disposed opposite to each other in the left-right direction. In the left-right direction, the first sidewall 221 is located on the side of the second sidewall 222 away from the center of the front panel 24. The second sidewall 222 extends obliquely in the direction from back to front. By making the second sidewall 222 of the secondary air duct 22 extend obliquely in the direction from back to front, at least part of the airflow in the secondary air duct 22 can be guided towards the front of the front panel component 2, so that the airflow is more concentrated and blown towards the front center of the air conditioner, avoiding the airflow from being dispersed to other unnecessary directions, thereby improving the utilization rate of the airflow and thus more effectively regulating the temperature in front of the air conditioner.

[0073] In the left-right direction, the second sidewall 222 is spaced apart from the outer edge of the front panel 24, so that there is a certain gap between the second sidewall 222 and the outer edge of the front panel 24. This ensures that the airflow blown from the secondary air outlet 251 is spaced apart from the front panel 24 in the left-right direction, thereby reducing the possibility of condensation due to the large temperature difference between the airflow at the secondary air outlet 251 and the front panel 24.

[0074] refer to Figure 10 and Figure 11According to some embodiments of this utility model, the projection of the secondary air outlet 251 on the horizontal plane is the first projection, the projection of the second side wall 222 on the horizontal plane is the second projection, and the projection of the front panel 24 on the horizontal plane is the third projection. The intersection of the extension line of the second projection and the first projection is the intersection point A. The left and right sides of the third projection are the panel sides, respectively. In the left and right direction, the distance between the panel side on the same side and the intersection point A is L, which satisfies: L≥5mm. For example, L can be 5mm, 6mm, 7mm, 8mm, 9mm, etc. By L≥5mm, a larger distance can be made between the second side wall 222 and the panel side, so that the airflow blown from the secondary air outlet 251 and the panel side of the front panel 24 have a certain distance in the left and right direction. This can effectively reduce or avoid the possibility of condensation due to the large temperature difference between the airflow at the secondary air outlet 251 and the front panel 24.

[0075] refer to Figure 1 According to some embodiments of this utility model, the front panel 24 is a glass panel. The glass component allows the front panel 24 to have good light transmittance. For example, a display module is provided on the rear side of the front panel assembly 2. The light emitted by the display module can be smoothly transmitted to the outside of the panel through the light-transmitting part on the front panel 24, making it convenient for users to view the displayed content from the outside of the front panel 24. The projection of the secondary air outlet 251 on the horizontal plane is the first projection, the projection of the second side wall 222 on the horizontal plane is the second projection, and the projection of the front panel 24 on the horizontal plane is the third projection. The intersection of the extension line of the second projection and the first projection is the intersection point A. The left and right sides of the third projection are the panel sides, respectively. In the left and right direction, the distance between the panel side on the same side and the intersection point A is L, where L ≥ 5mm. This allows for a larger distance between the second side wall 222 and the glass panel, ensuring that the airflow from the secondary air outlet 251 and the glass panel have a certain distance in the left and right direction. This effectively reduces or avoids the possibility of condensation due to excessive temperature difference between the airflow at the secondary air outlet 251 and the glass panel.
